Friends, I need a formula which can extrapolate the values based on the % value changes. Here are below 2 examples with desired result what I need

E.g. (1)

I got difference of 10% (range between 50 to 60%) and difference in value is 50 (500 to 550). Hence for every % increase the value should also get increased by 5.

So I need a formula where if the percentage increases by 1% then my output should become **505 **and if % increased by 2% then my output should become **510**.

E.g. (2)

I got difference of 15% (range between 75 to 90%) and difference in value is 300 (1200 to 1500). Hence for every % increase the value should also get increased by 45.

So I need a formula where if the percentage increases by 1% then my output should become **1245 **and if % increased by 2% then my output should become **1290 **and so on.

These are 2 scenario and the range will change basis requirement.

Any help will be much appreciated
